The staff of light features a few special properties. When a combat spell (including curse spells like Confuse or Entangle) is cast with the staff, there is a 12.5% (1/8) chance that the staff will negate the rune cost for that spell. This chance increases to 20% when wearing combat robes, and 50% when wearing battle robes. Additionally, the staff of light can be used as a more accurate alternative to the slayer's staff for casting Slayer Dart.

Has a special attack, Miasmic Barrage, consumes 100% adrenaline and 100 charges on the staff (0.1% of maximum charge). A magic attack is launched at the opponent dealing up to 200% weapon damage, reduces their attack speed by a tick for 15 second, and halves their adrenaline gain for 15 seconds.
